1. LED display since the mid-1980s display, Shandong monochrome and full-color multicolor displays have come out, Linyi LED display initially animated screen text screen or early 90s hotel led display, Shandong LED development of computer display technology and integrated circuit technology makes LED video display technology to achieve, television images directly on the screen indoor led display, indoor full color especially the mid-1990s, blue and green high brightness LED research success and rapid production, Linyi color screen makes outdoor screen applications greatly expanded Jiangsu led display area in 100-300m range. Shandong full color LED display factories are in stadiums, squares, streets and even the venue, shopping malls have been widely Applications. It is a color screen semiconductor diode Shandong Linyi color screen can put energy into light energy. Light-emitting diodes and ordinary diode LED chip LED chip development, like the development of the tube is composed of a PN junction, Shandong full color also has a one-way conductivity. Linyi full color when coupled to a light emitting diode forward voltage, full-color injected from the P region to region and from the hole N N area electron injected into the P region, Shandong LED display near the PN junction within a few microns, respectively N electron-hole recombination zone and P zone, resulting in the spontaneous emission of fluorescence. Energy states of electrons and holes which different Linyi LED full color different semiconductor materials. Full color led display, Zaozhuang display, provided by the Hong Thai Optical Electronics Co., Ltd. Linyi Hong Thai. Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) strong, credible, in Linyi display equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Hong Thai Optical into the brilliant and you work for a better future!
